Hi,
I am trying to hide add display custom text in a theme but i don't want to edit the theme's footer. For this i like to use add_filter
add_filter( 'WHICH TAG CAN I USE?', 'my_footer_text' );
function my_footer_text( $default_text ) {
$ret = '<style type="text/css">
.copyright { visibility: hidden; }</style>';
$ret .= '<span id="footer-thankyou">Say Thankyou<span> | Powered by <a href="http://www.wordpress.org">WordPress</a>';
return $ret;
}
